Construct validity and responsiveness of Movakic: An instrument for the evaluation of motor abilities in children with severe multiple disabilities

The relationship between motor abilities and quality of life in children with severe multiple disabilities

“…An earlier study on the responsiveness and validity of Movakic showed the importance and multitude of life events that children with SMD have to deal with (Mensch et al . ). Therefore, the relationship between carefully inventoried events (e.g.…”

“…It should be noted that the motor ability of children with SMD is severely compromised and support is often needed for them to complete daily activities; this was an important fact in the development of Movakic. The expert group concluded that in this group of children, motor abilities are mostly based on support from other persons through facilitation of movement and support through assistive devices in combination with activity of the child (Mensch, Rameckers, Echteld, Penning, and Evenhuis, ). As was shown in this latter study, the tests available to evaluate motor abilities, applicable to children with motor disabilities, did not allow for manual support.…”

“…This instrument was developed because instruments applicable to children with severe disabilities were largely lacking (Mensch et al . ) and the existing tests were inadequate (Mensch, Rameckers, Echteld, Penning, and Evenhuis, ).…”

“…Movakic has been judged clinically relevant and suitable for the target population and has adequate content validity (Mensch, Rameckers, Echteld, Penning, and Evenhuis, ). Its test–retest and inter‐rater reliability are excellent or good (ICC 0.72–0.98) (Mensch et al .…”

“…Its test–retest and inter‐rater reliability are excellent or good (ICC 0.72–0.98) (Mensch et al . ), its construct validity is good ( r = 0.50–0.71), and Movakic is responsive to change resulting from events that might impact motor ability (Mensch et al . ).…”
